2. The above is the adjustment method of 2. 1 speaker, because the bass power of 2. 1 speaker is relatively large, and the mid-high power is small. If you don't adjust it, there will be too many bass and too few trebles, and the sound will be turbid and unpleasant.
3, 2.0 speaker bass is less, you can appropriately reduce the treble, bass will be more prominent. However, the circuit of 1080 reduces the treble, so this speaker can't reduce the treble, only the bass.
4. You don't need to adjust the sound effect when listening. The treble should be clear and delicate, the midrange should be full and bright, and the bass should have a little rhythm. Because bass is just a rhythm, not the main theme of music, people who only listen to bass are people who don't understand music.
Audio equipment consists of sound source (music playing equipment, microphone), control equipment (analog or digital mixer), audio processor (peripheral equipment such as effector, equalizer, voltage limiter, frequency divider, signal distributor, time delay and digital system controller integrating the above functions), power amplifier (power amplifier) and speaker.
The above equipment is used by connecting various types of wires and cables in series.
The development history of audio technology can be divided into five stages: vacuum triode, electron tube, transistor, integrated circuit and field effect tube.
Triode:
1906, American deforest invented the vacuum triode, which pioneered the electro-acoustic technology of human beings. 1927, Bell Laboratories invented negative feedback technology, which brought the development of audio technology into a new era. As a representative example, Williamson amplifier successfully applied negative feedback technology, which greatly reduced the distortion of the amplifier.
